Appnote—your unique style in the world of notebooks. Every note becomes a story, and every idea comes to life in an elegant interface. Appnote is designed to bring your creative thoughts to life and organize them. Here, even mundane notes become works of art. UNLIMITED CREATIVITY Create an unlimited number of folders and notes—your ideas know no bounds. Nest folders, build your own structure, and find what you need with a single tap. And if you've already created the content, add it in its entirety. PDFs, DOCX files, and images become full-fledged entries in the list: with a thumbnail preview, their own name, and instant viewing, without any extra steps. TEXT THE WAY YOU WANT A full-fledged rich text editor right in your pocket: • fonts, sizes, styles, and colors—highlight what's important the way you want; • Bulleted and numbered lists, as well as to-do lists with checkboxes that are easy to mark; • Hyperlinks, horizontal lines, and quick formatting clearing; • Instant undo – made a mistake? Just redo it; • Read-only mode to avoid accidentally editing a completed note. Links in the text work just like real ones: one tap and you're on the desired page. And if you prefer a more relaxed editing experience, tap-to-click navigation can be disabled in the settings. BRING YOUR NOTES TO LIFE Add images, videos, PDFs, and DOCX documents, and insert images directly from the clipboard. View attachments in the built-in gallery, maximize them to full screen, save them to your device, or open them in your favorite external app. Edited a file in another program? Appnote will notice the changes and offer to replace the original file or place the new version nearby. EVERYTHING AT YOUR FINGERTIPS • Favorites — the most important notes always come first. • Recent — quickly return to what you were just working on. • Instantly search all notes and search within an open note to jump to the desired section. • Sort by alphabetical order, creation date, modification date, or custom order. TASK Deleted notes no longer disappear without a trace. They are sent to the Trash, from where you can restore them with a single tap or permanently delete them. You choose the retention period — from "delete immediately" to any number of days. EASY SHARING • Send notes, images, and documents to other apps using "Share." • Save a note as a file — plain text or HTML, preserving styles and attached media files. • Forward a note as a single .appnote file—including all attachments—and import it back on another device in one step. • Receive text, images, videos, and PDFs from other apps: Appnote will ask whether to create a new note or append to an existing one. FULLY PERSONALIZED Appnote adapts to you, not the other way around: • Light and dark themes, background wallpaper, text colors, note backgrounds, and list card colors; • Number of columns and font size in the note list; • Custom icons for notes and folders—to the left or above the title, with a caption consisting of the first letters of the title on the ruled lines; • Indents, default image size, autosave, and other little touches that make your experience more convenient. SECURITY AND RELIABILITY • Password protection and biometric login. • Auto-lock when minimized—immediately, after a set number of minutes, or never. • Backup to a local folder, iCloud, or the cloud—with detailed statistics by file type. • Sync with Google Drive: notes, attachments, and settings are always up to date across all your devices. WHEREVER YOU WORK Appnote speaks 16 languages, including right-to-left languages, and works on iOS and Android smartphones and tablets. Dive into the world of Appnote—an app where style, convenience, and security come together in one exceptional product. Never lose your ideas again: they're always at your fingertips.

ReceptionRating · Positive reviews · Number of ratings

Lock Notes holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Lock Notes has 137 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 57% of Lock Notes's written reviews are positive against 85% of Appnote's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Lock Notes ships an update every 10 days, Appnote every 2 months. The most recent releases landed on September 22, 2026 and September 7, 2026 respectively.
